Can Thylacines Be Brought Back?

Plans to clone the thylacine were widely discussed in the media, starting around 1999; see
first story,
second story,
and third story.
However attempts by the Australian museum to create a thylacine genomic
library were unsuccessful:

second story.
A news story in May 2005 reported that the project had been picked up by another group.

The sticking point for resurrecting the thylacine is likely to be the
absence of a sufficiently close living relative to supply eggs and act as a
surrogate. If, however, it were somehow possible to boot up the thylacine
genome in a living cell, then things would be looking up. The interesting
thing about marsupials as opposed to other mammals is that pregnancy is so
short, usually lasting just a matter of weeks. This means the thylacine's
dependence on a surrogate mother would be much less than for mammals with a
long gestation period. Once born at only a few millimeters in size it might
be possible to feed a baby thylacine milk in an artificial pouch.
